API Downhole Pump Tubing pump 30-275THC 20-4-2 with 38CrMoAi Steel Barrel 20Ft Spray metal plunger

Product Desciption

The pump barrel assembly of the tubing pump connected on the tubing string,and with its down to the bottom of the well.Plunger assembly connected on the sucker rod string and with it down to the pump barrel position in the well,then with it do up and down reciprocating motion, so as to realize the production process.

In the process of production, when traveling valve and standing valve appear problems,we can pull the traveling valve and standing valve out the well through the sucker rod string, plunger and the puller ,instead of pull the whole pump and tubing string out of the well, reduce the labor intensity of operation, reduce the operation cost.
